The iris is colored with pastels and glitter, then coated with resin. It is made with gypsum and non-yellowing resin, so it will last a long time without discoloration. These are 14mm eyes with a 7mm iris. Photos were taken in a bright room, without the use of a photography light. Please note that the colors may appear different depending on the viewing environment. There may be some dust and air bubbles. I try to avoid noticeable bubbles, but please refrain from purchasing if you are looking for perfection. I also sell 12mm eyes, so please take a look if you're interested! *Shipping is free for doll items, so there is no discount for combined purchases. Ball-jointed doll Doll doll bjd resin
